Anything on cross-stitch?

Possibly, although this group is mostly devoted to "sewing" e.g.. garment, home dec, etc. there are people with many skills "here".

Are you interested in hand or machine embroidery? There is a group devoted to machine embroidery: alt.sewing.mach-embroider.

What is your question?

rec.crafts.textiles.needlework is more active than this group, and probably has a higher percentage of hand embroiderers. The current thread is about beading, but I'm pretty sure that I've seen cross-stitch discussed.

On the other hand, this group contains a surprising amount of knowledge for its size.

I've done lots of cross stitching over a few decades. It's one of the less challenging forms of embroidery IMO.
